Wood has been utilized by humans since antiquity. Trees provided a source of many products required by early humans such as food, medicine, fuel, and tools. For example, the bark of the willow tree, when chewed, was used as a painkiller in early Greece and was the precursor of the present-day aspirin.

2011 IEEE Industry Applications Society Annual Meeting, 2011
Triboelectrification between a variety of woods and polytetrafluoroethylene (PTFE) is studied. The saturation charge developed on a PTFE sphere rolling on inclined planes of 11 different commercially available woods was measured. The results suggest that the saturation charge levels are positively correlated with the area of contact.

From Trees to Wood or Wood to Trees?
Journal of Surgical Research, 2008Derish and Eastwood draw on years of combined experience helping surgeons write clearly for their intended readers [1]. Their approach is bottom-up, starting with words, then sentences, then paragraphs. They are to be congratulated for condensing into a small “clarity clinic” much of the material that has appeared in many monographs on the subject over

Significance of wood extractives for wood bonding
Applied Microbiology and Biotechnology, 2015Wood contains primary extractives, which are present in all woods, and secondary extractives, which are confined in certain wood species. Extractives in wood play a major role in wood-bonding processes, as they can contribute to or determine the bonding relevant properties of wood such as acidity and wettability. Therefore, extractives play an immanent

British Journal of Dermatology, 1976
Eighty-three cases of dermatitis caused by wood or sawdust have been seen at St John's Hospital for Dieases of the Skin, London, in the last 20 years. The clinical details and results of patch tests are reported. The literature on dermatitis, mucosal irritation, asthma and other toxic effects of woods of some 300 botanical species is reviewed at length,

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2002
The rotary machining process as applied to timber is introduced and compared with the milling and grinding of metals. The emphasis of this work is on the waviness surface quality of the machined timber and initially focuses on a review of the techniques applied to improve surface quality at higher workpiece feed velocities—typically 120 m/min. The main
